Because food has been broken down, so the tract can get smaller.
This is called mucous. You make about one liter per day in the digestive tract. You also make some in the respiratory tract, urinary tract and the reproductive tract. Any system that has a connection to the outside makes mucous. All others (internal organs) make serous fluid as a sort of bath.
The outpockets of an anterior digestive tract that may develop into respiratory structures are called respiratory diverticula. These diverticula are found in organisms like insects and some mollusks, where they eventually form into structures like tracheae or lungs for gas exchange.
The gastrointestinal tract contains sphincters, which are circular muscles that regulate the movement of material through the digestive system. Some examples of sphincters in the gastrointestinal tract include the lower esophageal sphincter, pyloric sphincter, and anal sphincter.
There is more than one system that removes wastes from the body. The urinary system is probably the most familiar (urine), the digestive tract (feces), the respiratory tract (carbon dioxide) and the integumentary (skin) removes water and some electrolytes.
The space is called the coelum, and provides cushioning of the digestive system in earthworms and some other simple animals. It allows the organs to function independently of the external structures.
Mammals have a complete digestive tract, it starts from mouth to anus. Although each species have some different type and length of tract, they have esophagus, ventriculus, intestinum which function to support a complete food metabolism. Besides, some digestive glands also support this function.
Leeches have a complete digestive tract. Leeches are members of Phylum Annelida. This phylum has the general characteristic of having a complete digestive tract, i.e. food goes in through the mouth, pass through digestive tract of some sort like stomach and/or intestine, waste gets discarded through some sort of rectal opening, i.e. anus. In comparison, an incomplete digestive tract generally means food goes in and waste come out of the same opening, i.e. mouth=anus. Lower level invertebrates have incomplete digestive tract like Phylum Cnidaria and Phylum Platyhelminthes members.
of course they defecate , and it smells gross some people EAT there defecate in places like Norfolk !!! When a person "de-veins" a prawn, they're actually removing the digestive tract, and essentially, the faeces.
due to the chonigal order it some that i do not prosess in my brain......
eat healthy. eat tyler lawson
It would cause some pretty serious bleeding in the digestive tract.
I think you are looking for liver and pancreas, these are accessory digestive organs that produce enzymes and emulsifiers that are secreted into the digestive tract.
yes it can mess with your nerves cells

Not really. It can absorb some posions that are still in your stomach /digestive tract, but that's pretty much it.
Some of the major organs in the Digestive System are the: Esophagus, Stomach, Duodenum, Small Intestines, Large Intestines(Colon), Pancreas, Gallbladder, Rectum, and Anus. Edited by Dylan Dang
